I need to replace the crap battery in my 310 GK. I discharged it all the way and I think it sat out and got frozen as it lasts less than 8 hours with just a couple of lights on. I am thinking of getting two lithium batteries at 100 Ah. Would anyone be able to recommend a new converter for this set up? I know the progressives are there for lithium batteries but I don’t know what size I should get and if I need a bigger one whether I need to Change the wires from the converter to the battery and panels.

Finally if anyone in Canada can recommend a good dealer for decent lithium batteries would certainly be appreciated. There are cheap ones on Amazon but I’m a little concerned about the quality

Thanks
